Overview of 1261 Madison Avenue

1261 Madison Avenue is a distinguished Beaux Arts co-op located in the heart of Carnegie Hill, designed by Buchman & Fox and completed in 1901. This landmarked building features a striking mansard roof and a rusticated limestone base, housing just 14 apartments across seven stories. The intimate setting is complemented by a live-in superintendent, a central laundry room, bike storage, and private storage options. The building permits pied-à-terre arrangements and pets, with 50% financing allowed and a 2% flip tax paid by the buyer.

The apartments at 1261 Madison Avenue are characterized by their spacious layouts and original architectural details. Many units boast high ceilings, oversized windows, and classic moldings, with some featuring decorative fireplaces and preserved oak hardwood floors. Notable apartments include a grand half-floor residence with a 31-foot double living room and a library that can be combined for a loft-like feel. The windowed eat-in kitchens offer ample design potential, and many units have been recently renovated to include modern amenities while retaining their historic charm.

The building's prime location is just a block from the Jacqueline Kennedy Onassis Reservoir and surrounded by the cultural richness of Carnegie Hill, including museums, restaurants, and boutique shopping. Residents enjoy easy access to public transportation, making it a convenient choice for city living. The neighborhood is known for its beautiful townhouses and family-friendly atmosphere, further enhancing the appeal of this unique co-op.

Broker & Buyer Comments

Add Your Own Comment

This "handsome" pre-war residence in historic Carnegie Hill offers "generous" three-bedroom layouts with "just two units per floor." The Madison Avenue address puts you in the heart of an area that "Andrew Carnegie himself helped develop," though some say the "distinguished facade" is easy to miss from the street. A classic example of "turn-of-the-century Upper East Side luxury."

Sales History

Price/Room (Est)

Why are we displaying the estimated price per room?

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.

By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
